Export the layout from cadence to hfss or from hfss to cadence.
Dear all, Is there anybody familiar with simulation of a layout extracted from cadence in hfss. Is there any voltage pulse generator source in hfss that we can use it with lumped port? Any comment is appreciated, Thanks,
If you have the tool cadence IC446 or cadence IC500, or cadence IC610. Look on the document section you will find the tutorial
someone can tell me how to print cadence layout to pdf file . I want to print some layers to pdf and print in papers!!!!
Hello all, I was wondering if there is a tool/methodology that converts Magic layout to cadence layout. What happened is my group has a chip layout design in Magic and we want to fabricate it. Since the layout is quite large, we are trying to see if there is a simple way to convert Magic (...)
Hello, I'd like to stream out in cadence layout selected nets containing all the attached polygons or, at least, the metal layers composing such nets. I know how to stream out selected layers by defining a layer map table in Stream options, but I need to stream out all layers composing selected nets still matching the original layout. Can (...)
Hi, I am a beginner of hfss. Currently I met a problem about the model extraction between cadence and hfss and was wondering if anyone could give me help. I want to first extract a device model in cadence such as an inductor to hfss and simulate it in hfss because I don't trust the (...)
51976 I recently worked on cadence layout XL where my task was to design a butterworth filter to match a specification using ASIC Process.I started with CMOS level schematic - to testing the schematic - extracting it to form an extracted Op-Amp - using the Op-Amp to make an 8th order butterworth filter. (and to extract the filt
Does anyone know how to use Skill code to show the layers used in the current cadence layout window? That is, only for the layers shown on the current Virtuoso layout window. Thanks.
Can any one send me the complete layout tutorial?
this sites is for fabrication/layout process a book on asic digital gives idea abt cadence tool(spectre etc)
Design with other layout editor as magic and then export to cadence in GDSII format. Bastos
From L-Edit, export your design in GDS2 format, then stream in the GDS data into Virtuoso. Please make sure that the GDS layers between Tanner and cadence are the same.
Try and check the .cdsenv file in your cadence Home directory. You will have a field for the layout editor Background..... I am not sure from here.But with some browsing, it will be done.....I hope that it helps...
Hi I am trying to export a layout from cadence to a .eps file to import in a LaTeX doc, but the eps file is very heavy (3 MB) even with a small design (100 mu x 300 mu in 0.35 mu tech.). Has anyone found a way to reduce this ? Regards, Peter
goto the newsgroup: comp.cad.cadence they will provide the information or at least point you in the right direction.
Maybe your version lost few librarys. You can copy these librarys at another person also have cadence. Or you can use L-edit (Tanner EDA) to draw layout(Tanner have version 7.12 for student,you can download free)!
Maybe you are using the extractor of Diva. There are better tools which can also work with virtuoso. The two mostly used are Assura from cadence and Calibre from Mentor.
Hi, can anyone help me about this? I am using ST 0.13um designkits in cadence. when I am trying to make some layout and DRC, there is an error : ' Poly without implant not allowed'. Can anyone tell me that does this mean? Thanks a lot.
I have created my dxf file in MWO. I then try to import the file to cadence to do some layout but the import always comes up with a blank layout. I have only the thickmetal layer selected in MWO.
If you just want a example for a start, you can copy from the cadence installation directory. Maybe you need other tools for DRC. Diva is not so powerful and efficient for 0.25um technology.
i am unable to DRC on my layout . It says No DRC or DRC License (312) is available. I have checked my license file there is drc license available. Please suggest something as i have not found anything which helps me out even on cadence Sourcelink database. This is output after i run the drc in
For cadence layout, do you guys like to generate layout cells from schematic via Virtuoso XL, or prefer to instantiate your own cells and then manually correspond the devices in schematic with the layout? For me, I have had trouble mapping multiple devices in schematic with my designed multi-fingered (interdigitated) (...)
hi everyone to perform LVS of an inductor in IBM cms9flp on cadence, i need to draw a guard ring around the inductor. when i try to draw a guard ring around the inductor using layout Editor-->Create-->Guard Ring this error message which was generated *WARNING* (LE-103399): leHiCreateGuardRing: The create guard ring command requires MPP guard
Even it directly interfaces to cadence Virtuoso... Here's a description of the design flow for Sonnet within the cadence RFIC environment: See page 15 ff for a design flow overview with some screenshots. For interconnect/lines, you m

hi i am using cadence 5.1.41 on a redhat platform. i have generated a symbol for a schematics and the check option shows no errors. yot when i go to design synthesis layout xl and try to extract a layout a errror pops up saying there is no lx extract layer info in my cdsDefTechLib library what is the error and how do i get rid of (...)
I am using cadence LE for doing layout.If I try to make summary report or tree hirachy list from 'design' menu an error window comes.The error is as follows "Cannot create View file /tmp/Summarya27670" I checked the permission to craete a file in /tmp/ folder. I have write permission in that folder.
I have extracted PI model parasitics of inductor in ASITIC and imported CIF file in cadence. It is visible in cadence layout window. How to use this layout of inductor in my LNA (low noise amplifier) circuit and layout for Schematic and DRC ,LVS respectively. Please help me its very urgent for me. waiting (...)
Hi All, I imported a design from cadence into hfss using GDS. Now my problem is I cannot see the coordinates of the geometric solid. Can anyone help me with this? I imported a transformer and I needed to add definitions for the silicon dioxide and substrate, which I plan to add in hfss since cadence does not do this in (...)
Dear Friends I would like to know if any of you has a simple help, tutorial and example of (for example: an inverter) how to layout and post simulate a circuit in cadence 6.1. I do appreciate it. Regards, Samaneh
Hi, I have just installed a new PDK on my cadence IC 6.1.4, and I have the following errors that I cannot solve! : 1/ When I launch cadence IC6.1.4 with the command: "virtuoso", I can see in the CIW window that the initialization runs a lot of time and finally ends with : "*Error* unknown: Value Stack Overflow!!!

Hello, I am using the very useful NCSU design kit for creating masks for microfabrication. I have a major frustration which is the grid spacing is always reset when a new layout is opened. I would like to take this opportunity to create a script (ocean?!) in cadence icfb (5.14) to change the x and y snap spacing with a hotkey. Can someone p
If you don't get an answer either here or on your thread in the EDAboard forum, you could still ask in the cadence Custom IC Design forum. I guess they will happily answer!
I meet thease DRC errors in my layout in cadence 1. off grid polygon in layer poly, NIMP or... 2.figure having no stamped connectionS. N+SD to Psub tap spacing must be <=10u it should be mentioned that thease errors occur even i draw only one transistor using its standard library (create->instance) I use IC5141 and 0.18um GPDK (...)
Hi,everyone, There is a warning "gate used as conductor" after DRC when I use cadence to create layout. The layout is shown in the figure. What's the meaning of the warning? Does that mean I can't connect two transistor's gate using poly? Thanks.87828
hello, i am new to analog cadence design..i want to ask is it the cadence can automatic layout from the schematic that we draw..??how to carry out it..?? Can somebody teach me..?? Thanks~~~ :-)
Iam drawing a layout in cadence for a 2 input nand the Pull down network i used a p substrate for each of the NMOS. For the lower NMOS i connected the substrate to Ground.But, when i connect the substrate of the upper NMOS to the its source as in the schematic,i get the errors "p substrate stamp error mult,psubstrate stamp error connect" i
